Cold atmospheric plasma (CAP) has emerged as a promising alternative to chemical seed treatments because of its antimicrobial activity, although its effects on fungal communities associated with developing seedlings remain poorly understood. Here, Arabidopsis thaliana seeds from two ecotypes (Columbia and Landsberg erecta) were exposed to CAP for 5 or 15 min. Seed decontamination efficiency was assessed by culturing on malt extract agar and nephelometric analyses, while fungal communities associated with seedlings derived from treated and untreated seeds were characterized by ITS1 amplicon sequencing. CAP efficiently reduced fungal contamination without affecting seed germination. CAP altered the composition of fungal communities associated with developing seedlings, but the magnitude of these changes depended on seed batch and ecotype. Dominant taxa markedly declined after treatment, whereas several low-abundance taxa increased in relative abundance. These findings demonstrate that CAP is an effective pesticide-free technology for seed decontamination and can also reshape fungal communities associated with developing seedlings, highlighting broader ecological consequences of plasma-based seed treatments.<\/jats:p>","DOI":"10.3390\/plants15172719","type":"journal-article","created":{"date-parts":[[2026,9,4]],"date-time":"2026-09-04T16:07:32Z","timestamp":1788538052000},"page":"2719","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cold Atmospheric Plasma Decontaminates Arabidopsis thaliana Seeds and Remodels Seedling Fungal Microbiota"],"prefix":"10.3390","volume":"15","author":[{"given":"L\u00e9na","family":"Taras","sequence":"first","affiliation":[{"name":"Development, Adaptation and Ageing (Dev2A), Sorbonne Universit\u00e9, CNRS, Inserm, F-75005 Paris, France"},{"name":"Institut de Biologie Paris-Seine (IBPS), Sorbonne Universit\u00e9, CNRS, Inserm, F-75005 Paris, France"},{"name":"Laboratoire de Physique des Plasmas (LPP), Sorbonne Universit\u00e9, CNRS, \u00c9cole Polytechnique, F-75005 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2894-9333","authenticated-orcid":false,"given":"Nicole","family":"Chaumont","sequence":"additional","affiliation":[{"name":"Development, Adaptation and Ageing (Dev2A), Sorbonne Universit\u00e9, CNRS, Inserm, F-75005 Paris, France"},{"name":"Institut de Biologie Paris-Seine (IBPS), Sorbonne Universit\u00e9, CNRS, Inserm, F-75005 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Kunz","sequence":"additional","affiliation":[{"name":"Unit\u00e9 Mol\u00e9cules de Communication et Adaptation des Micro-Organismes, Mus\u00e9um National d\u2019Histoire Naturelle, UMR 7245, F-75005 Paris, France"},{"name":"Facult\u00e9 des Sciences et Ing\u00e9nierie, Sorbonne Universit\u00e9, UFR 927, F-75005 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0397-368X","authenticated-orcid":false,"given":"Thierry","family":"Dufour","sequence":"additional","affiliation":[{"name":"Laboratoire de Physique des Plasmas (LPP), Sorbonne Universit\u00e9, CNRS, \u00c9cole Polytechnique, F-75005 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5878-9249","authenticated-orcid":false,"given":"Christophe","family":"Bailly","sequence":"additional","affiliation":[{"name":"Development, Adaptation and Ageing (Dev2A), Sorbonne Universit\u00e9, CNRS, Inserm, F-75005 Paris, France"},{"name":"Institut de Biologie Paris-Seine (IBPS), Sorbonne Universit\u00e9, CNRS, Inserm, F-75005 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,4]]},"reference":[{"key":"ref_1","unstructured":"FAO (Food and Agriculture Organization of the United Nations) (2026, September 01).
